PETER M. KLING, OF ST. LOUIS, MISSOURI.

CAR-TRUCK.

SPECIFICATION forming part of Letters ?atent No. 621,826, dated March28, 1899.-

Application filed December 1,1898. Serial No. 697,970. (No model.)

T0 to whom it may concern:

Be it known that I, PETER M. KLING, a citizen of the United States,residing at the city of St. Louis, in the State of Missouri, haveinvented certain new-and useful Improvements inOar-Trucks, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, forming part of this specification.

My presentinvention relates to an improved side bearing for car-trucks,and is more particularly intended for street-car trucks.

My invention consists in features of novelty hereinafter fullydescribed, and pointed out in the claims.

Figure I is a perspective view of a car-truck embodying my improvement.Fig. II is an enlarged vertical longitudinal section taken through oneof the side bearings. Fig. III is a vertical transverse section thereof.

1 represents the side bars of the truck. The truck, per 86, may be ofany desired construction. The central portions of the side bars areformed with integral enlargements 2, these enlargements having pockets3, which are open at top, so as to receive blocks 4, that form the sidebearings of the body-bolster. The lower faces of the blocks 4 arerecessed, so as to provide inverted pockets 5 to receive the upper endsof springs 6, the lower ends of which rest on the bottoms 7 of thepockets 3. The blocks or side bearings are thus spring-supported, andthey are held in the pockets by bolts 8, that pass up through a wall 9beneath the top 10 of each block. The top 10 of each side bearing is aseparate piece and is held between lugs 9 by a bolt 9*, the lugsextending upwardly from the Wall 9, as shown in Fig. III.

11 represents the truck-bolster, having the usual king-bolt hole 12 andwhich is supported by the side bearings through means of the bolts 8 andcross-pieces 13,held by the bolts and upon which the ends ofthe bolsterrest. The bolster is thus carried by the same springs that support theside bearings, so that the load carried by the car affects both alike sofar as vertical strain is concerned, and thus the vertical strain of theweight carried by the carbody does not cause the body to descend ontothe side bearings, which recede with the descent of the body.

I claim as my invention 1. The combination, in a car-truck, of side barseach provided with spring-supported side bearings, a bolster, and meansfor connecting the bolster, from beneath the side bars, to the sidebearings, substantially as set forth.

2. The combination, in a car-truck, of side bars each provided withspring-supported side bearings, a bolster, and rods connecting thebolster, from beneath the side bars, to the side bearings, substantiallyas and for the purpose set forth.

3. In a car-truck, the combination of side bars having pockets, sidebearings fitting in said pockets, springs located in said pockets andwhichsupport the side bearings, and a bolster suspended from said sidebearings, substantially as set forth.

at. In a car-truck, the combination of side bars having integralenlargements formed in their central portions, side bearings fitting inpockets in said enlargements, springs located in said pockets, and whichsupport said side bearings, a bolster, and rods supporting said bolsterfrom said side bearings, substantially as set forth.

5. In a car-truck, the combination of side bars, side bearings, springssupported on the side bars, and a bolster carried from beneath the sidebars by the side bearings, substantially as set forth.

6. In a car-truck, the combination of side bars, provided with pockets,side bearings fitting in said pockets, springs located in the pocketsand upon which the side bearings rest, rods extending from the sidebearings down through the side frames, cross-pieces carried by saidrods, and a bolster resting upon said cross-pieces, substantially as setforth.

P. M. KLING. In presence of E. S. KNIGHT, STANLEY STONER.
